Abstract (en)
[origin: WO2004049623A1] The invention relates to a communication system using quantum cryptography, comprising subscriber stations (l.i, 2.i) which are connected to quantum channels (3) and quantum-cryptographic devices (10, 11) which are associated with the quantum channels and are used to generate a quantum key. Said communication system comprises a plurality of interconnected switching stations (1, 2) to which the subscriber stations (1.i, 2.i) are connected by means of the quantum channels (3) in order to generate a respective temporary quantum key.
